Yours is a complete reversal of my findings.
A recent visitor to my music group brought a Classic Records RCA repress that he had cleaned with his VPI machine and Disc Doctor fluid. We had been playing my LP's (which are all cleaned with RR fluid) for about an hour when he ask if I would play a selection from his record. This record exhibited more background noise than any selection of the evening.
One point of your review on which we (appear) to agree. The Disc Doctor fluid results in a recessed and darker presentation. In addition, the DD fluid delivers less resolution, sparkle and extension in high frequencies when compared to my Record Research cleaned LP's.
Having experienced this myself with Disc Doctor, I ask permission to reclean his record. I used my VPI machine and applied Record Research Deep Clean, followed by Record Research Vinyl wash. We then played the same selection as before.
There were six people listening that evening and the results were so obvious that the count was six to zero in favor of the Record Research. Quieter background, lower distortion and extended bandwidth.
Based on comments on this thread, this must be a system thing, those who like the darker sound or the clearer sound. The good thing about Record Research is that I does require rinsing. The reason the Disc Doctor spreads around the LP so well is because it DOES contain surfactants that are difficult to rinse and why it benefits from a water wash afterward.
If you rinsed it enough to remove ALL traces, you might get sound similar to what is achieved with the Record Research (two solution) combo.
